An isolated concrete pavement slab of length L is resting on a frictionless base.
The temperature of the top and bottom fibre of the slab are Tt and Tb, respectively.
Given: the coefficient of thermal expansion = α and the elastic modulus = E. Assuming Tt > Tb and the unit weight of concrete as zero, the maximum thermal stress is calculated as _______.
